We find that the attractive and repulsive Yukawa potential between nucleons is modified by the variation of Debye mass directly and, especially, the nucleon system described by this Yukawa potential will be unbounded at some critical T and μ.

文摘From the Lagrangian density of QHD-I model, we study the properties of hot and dense nuclear matter when the zero-point correction is considered and find that the influence of zero-point correction is very important at high temperature.
